[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] refer to Figures 1-3 As shown, this utility model embodiment provides a patch adhesive backing cutting and positioning structure, specifically including a receiving plate 1; the receiving plate 1 is sequentially provided with an installation component 3, a guide component 2, a sliding frame 410 and a clamping component 440; a first telescopic cylinder 433 is installed on the sliding frame 410, and a positioning component 430 and a cutting component 420 are installed on the telescopic end of the first telescopic cylinder 433. The positioning component 430 and the cutting component 420 are sequentially arranged along the direction away from the installation component 3, and the positioning component 430 is closer to the receiving plate 1 than the cutting component 420; The mounting assembly 3 is used to mount the adhesive roll; the guide assembly 2 is used to guide the end of the adhesive roll onto the receiving plate 1; the clamping assembly 440 is used to clamp the end of the adhesive roll, causing the end of the adhesive roll to pass through the positioning assembly 430 and the cutting assembly 420; the first telescopic cylinder 433 is used to drive the positioning assembly 430 and the cutting assembly 420 to descend; the positioning assembly 430 is used to press and position the middle part of the adhesive roll, and the cutting assembly 420 is used to cut the middle part of the adhesive roll, thereby cutting the end of the adhesive roll out from the adhesive roll. The middle part of the adhesive roll refers to a portion between the end of the adhesive roll and the body of the adhesive roll; Specifically, the principle of the adhesive backing cutting and positioning structure is as follows: First, the adhesive backing roll is installed using the mounting component 3. Then, the end of the adhesive backing roll is manually removed and guided by the guide component 2. Next, the guide component 2 guides the end of the adhesive backing roll to the receiving plate 1, where the clamping component 440 clamps the end of the adhesive backing roll, allowing it to pass through the positioning component 430 and the cutting component 420. Then, the telescopic end of the first telescopic cylinder 433 lowers the positioning component 430 and the cutting component 420, causing the positioning component 430 to press against the middle of the positioned adhesive backing roll, and the cutting component 420 to cut the middle of the adhesive backing roll, thus cutting the end of the adhesive backing roll off the roll. During this process, the positions of the positioning component 430 and the cutting component 420 can be adjusted using the movable frame 442.

[0023] refer to Figure 1 , Figure 2 and Figure 3 As shown, the guide assembly 2 includes: a drive motor 201, a first rolling roller 202, a second rolling roller 203, a fixed frame 204, and a second telescopic cylinder 205. The output end of the drive motor 201 is fixedly connected to the first rolling roller 202. The second rolling roller 203 is disposed below the first rolling roller 202. The first rolling roller 202 and the second rolling roller 203 are respectively rotatably connected to the fixed frame 204. The second telescopic cylinder 205 is disposed below the drive motor 201. The side of the fixed frame 204 is fixedly connected to the second telescopic cylinder 205. The telescopic end of the second telescopic cylinder 205 is fixedly connected to the cutting assembly 420. A rack plate 206 is slidably connected to the other end of the fixed frame 204. A gear 207 meshes with the rack plate 206. The side of the gear 207 is fixedly connected to the second rolling roller 203. The side of the rack plate 206 is fixedly connected to the adjusting cylinder 208. An auxiliary cylinder 209 is fixedly placed inside the receiving plate 1 below the adjusting cylinder 208.

[0024] During use, the drive motor 201 is manually started, causing the drive motor 201 to drive the first rolling roller 202 to rotate within the fixed frame 204. The first rolling roller 202 pushes the adhesive backing to below the adjusting cylinder 208 through rotation, causing the second rolling roller 203 to be subjected to friction generated by the movement of the adhesive backing. Subsequently, the second rolling roller 203 starts to rotate, further pushing the adhesive backing. At the same time, the first rolling roller 202 drives the gear 207 to rotate. Then, the gear 207, through meshing, drives the rack plate 206 to move downward on the side of the fixed frame 204. The rack plate 206 drives the adjusting cylinder 208 to move downward and squeeze the adhesive backing downward. When the adjusting cylinder 208 squeezes the adhesive backing downward to the auxiliary cylinder 209 in the receiving plate 1, due to the supporting effect of the auxiliary cylinder 209, the auxiliary cylinder 209 pushes the adhesive backing upward. At this time, the adhesive backing is subjected to balanced forces from top to bottom, so that the adhesive backing straightens on the receiving plate 1 and no longer bends. At the same time, the clamping assembly 440 is activated to prepare to clamp the adhesive backing.

[0025] refer to Figure 1 and Figure 2 As shown, the mounting assembly 3 includes: a first mounting plate 301, a second mounting plate 302, and a first spring 303. The first mounting plate 301 is slidably connected to the receiving plate 1. A second mounting plate 302 is provided on the side of the first mounting plate 301, and the first mounting plate 301 and the second mounting plate 302 are connected by the first spring 303. The mounting assembly 3 also includes: a first mounting rod 304 and a second mounting rod 305. One end of the first mounting rod 304 is rotatably connected to the first mounting plate 301, and the second mounting rod 305 is rotatably connected to the second mounting plate 302.

[0026] During use, the adhesive backing roll is placed in the clamping position between the first mounting plate 301 and the second mounting plate 302, so that the first mounting plate 301 and the second mounting plate 302 slide on the receiving plate 1 according to the size of the adhesive backing roll. When the adhesive roll is small, the first mounting plate 301 and the second mounting plate 302 are pushed closer to each other, so that the first mounting plate 301 and the second mounting plate 302 respectively drive the first mounting rod 304 and the second mounting rod 305 to be inserted into the adhesive roll. When the first mounting plate 301 and the second mounting plate 302 are close to each other, the first mounting plate 301 and the second mounting plate 302 squeeze the first spring 303, causing the first spring 303 to contract. Then, the positioning bolt 9 on the positioning plate 8 is manually turned into the threaded hole 7 on the fixing plate 6 for fixing. When the adhesive roll is large, it is inserted into the first mounting rod 304 and the second mounting rod 305, causing the first mounting rod 304 and the second mounting rod 305 to be squeezed and pushed by the adhesive roll. Then, the first mounting rod 304 and the second mounting rod 305 respectively push the first mounting plate 301 and the second mounting plate 302 to slide back and forth on the receiving plate 1, causing the first mounting plate 301 and the second mounting plate 302 to stretch the first spring 303. Then, the first spring 303 extends, and then the positioning bolt 9 on the positioning plate 8 is manually turned into the threaded hole 7 on the fixing plate 6 for fixing.

[0027] refer to Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly 440 includes: a clamping plate 441, a movable frame 442, a slide rail 443, a third telescopic cylinder 444, and a fourth telescopic cylinder 445. The bottom end of the slide rail 443 is fixedly connected to the receiving plate 1. The inside of the slide rail 443 is slidably connected to the movable frame 442. The inner side of the movable frame 442 is slidably connected to the clamping plate 441. The clamping plate 441 is fixedly connected to the telescopic end of the fourth telescopic cylinder 445. The movable frame 442 is fixedly connected to the telescopic end of the fourth telescopic cylinder 445. The fourth telescopic cylinder 445 is fixedly connected to one end of the receiving plate 1.

[0028] When the adhesive end is located between the adjusting cylinder 208 and the auxiliary cylinder 209, a blower (not shown) is installed on the side of the receiving plate 1. The blower is then started to blow air on the side of the receiving plate. Since the adhesive is thin and the airflow from the blower is constant, it generates an upward airflow to support the adhesive and prevent the end of the adhesive roll from sagging or curling due to gravity and tension fluctuations. Then, the fourth telescopic cylinder 445 is manually activated, causing the telescopic end of the fourth telescopic cylinder 445 to push the moving frame 442 to move towards the fixed frame 204 within the slide rail 443. This moves the moving frame 442 above the end of the adhesive roll. Since the third telescopic cylinder 444 is controlled by an external infrared sensor and a solenoid valve, when the moving frame 442 moves the clamping plate 441 and the third telescopic cylinder 444 to the end of the adhesive roll, the external infrared sensor senses the end of the adhesive roll through infrared light and controls the solenoid valve to start. The third telescopic cylinder 444 causes its telescopic end to push the clamping plate 441 upward inside the moving frame 442. Then, the clamping plate 441 pushes the adhesive backing to cooperate with the moving frame 442 to clamp it. Then, the fourth telescopic cylinder 445 is closed, causing its telescopic end to drive the moving frame 442 to move towards the sliding frame 410. Thus, the moving frame 442, together with the clamping plate 441, pulls the end of the adhesive backing roll, causing the middle part of the adhesive backing roll to rotate through friction, driving the adjusting cylinder 208 and the auxiliary cylinder 209 to rotate. At the same time, the second rolling roller 203 rotates, and the adhesive backing roll rotates between the first mounting rod 304 and the second mounting rod 305. Thus, the adjusting cylinder 208 and the auxiliary cylinder 209 further push the adhesive backing to move faster towards the sliding frame 410 through rotation. The end of the adhesive backing clamped by the moving frame 442 and the clamping plate 441 passes under the sliding frame 410 and is stretched to one end of the receiving plate 1.

[0029] refer to Figure 1 and Figure 2 As shown, the cutting assembly 420 includes a connecting plate 421 and a cutter 422. The connecting plate 421 is fixedly connected to the telescopic end surface of the first telescopic cylinder 433. The cutter 422 is disposed below the connecting plate 421 and is fixedly connected to the telescopic end of the first telescopic cylinder 433. When the end of the adhesive backing passes below the sliding frame 410 and is stretched to one end of the receiving plate 1, the second telescopic cylinder 205 is manually activated, causing the telescopic end of the second telescopic cylinder 205 to drive the sliding frame 410 to slide horizontally in the sliding groove 5 on the side of the receiving plate 1. When the sliding frame 410 moves to a certain position above the adhesive backing, the first telescopic cylinder 433 is activated, causing the telescopic end of the first telescopic cylinder 433 to extend downward and push the cutter 422, causing the cutter 422 to move downward. At the same time, the downward movement of the cutter 422 will cause the connecting plate 421 to move downward simultaneously.

[0030] refer to Figure 1 and Figure 2As shown, the positioning component 430 includes: a telescopic column 431 and a pressing plate 432. The pressing plate 432 is disposed below the cutter 422. The top end of the pressing plate 432 is fixedly connected to the telescopic column 431. The telescopic column 431 and the cutter 422 are pressed together by a connecting plate 421.

[0031] When the cutter 422 moves the connecting plate 421 downwards, the connecting plate 421 moves the telescopic column 431 downwards. Subsequently, the telescopic rod moves the pressure plate 432 downwards. Since the pressure plate 432 is located below the cutter 422, it first presses against the positioning adhesive and stretches the second spring (not shown) fixedly connected between the sliding frame and the pressure plate. Simultaneously, the downward movement of the cutter 422 compresses the telescopic rod through the connecting plate 421, causing the telescopic column 431 to contract and compress the third telescopic spring inside (not shown). The cutter 422 continues to cut the adhesive backing downwards without being restricted by the pressure plate 432. After cutting, the first telescopic cylinder 433 is manually closed, causing the telescopic end of the first telescopic cylinder 433 to drive the cutter 422 upwards, and at the same time, the connecting plate 421 moves upwards synchronously. Then, the connecting plate 421 no longer squeezes and pushes the telescopic column 431, so that the second spring drives the pressure plate 432 upwards to reset through the rebound force, preparing for the next positioning. At the same time, the third telescopic spring inside the telescopic column 431 pushes the telescopic end to reset through the rebound force.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
